I understand the technical challenges with running x86 apps on arm… but multiple wrappers that do something similar to proton have already been released.

If you follow the r/emulationonandroid subreddit, they have gotten PC games working on android for a while now. One of the wrappers, gamehub, has made it to the playstore. You can just sign in to your steam account (don’t do that gamehub is sketchy af, proprietary, and by a company that stole gpl code fro, yuzu and didn’t release a derivative product), download games, and play them.

The current concern is performance, but most lower and midrange games run just fine.

This is only one half of the open source. Those scripts are not poweshell or bash scripts, but instead something simimar to Ansible, run through the Windows AME wizard.

Which I cannot find the source code for. Great!

I think this is the command line onlu version, but the GUI versiom appears to be closed source.

No, this one is different. It’s not an ISO you download (those are extremely sus and you would be right to be skeptical of them), but instead an open source set of scripts you apply to an existing Windows OS.

Edit: see my comment below, it seems to be partially closed source.
